Kleinsasser spent all 13 of his NFL seasons with the Vikings after being a second-round draft pick out of UND in 1999. He appeared in more games than any tight end in Vikings history. He retired after last season.

The Carrington native was a two-time NCAA Division II All America tight end while at UND in the late 1990s.

The 2012 class also includes John Christen, a tennis and wrestling standout in the 1980s, and Louise Ronnerman, a cross country and track star in the 1990s. UND’s 1997 NCAA Division I champion men’s hockey team also is being inducted. The ceremony is Sept. 29.
